When some of our French Immersion teachers asked me for a book they could read with their students that included same sex parents, I had to apologize. I had been looking for such a book for our library for quite awhile, but had found nothing. I promised to keep looking. Fortunately, I asked Evelyne from Chouette books to help and she found this one:

In this lovely story a teacher asks her students what they did during their holidays. When a boy named Martin says that he had a great holiday with his two dads, it sparks a grand discussion about diversity in families. Highly recommend as a read aloud, in the class library, in the school library, and for home.
